Quick question: My rented house has a garage with unfinished walls - the supports (about 1 every 2 feet) are exposed and there's only a thin wall with no insulation separating outside from inside. Say I were to find two holes in the supports around the middle of the beam (both vertically and horizontally) right across the garage from each other.. Could I slip some thin cord (7/64") through and hang from it? My cold garage would be perfect to test my hammock setup.
I'm 150# and they're about 15-20 feet apart.
I haven't found these holes yet, but if I did...think I'd be risking damaging anything?
